Currently this package targets quite an old version of relay-runtime (^4.0.0), I'm wondering if there were any existing plans or demand for bringing version up to date (11.x). I've taken a quick look and can see there'd be a few changes required as some of the Flow type signatures have changed since 4.x so I assume there may be some compatibility issues.
I assume this may result in a major breaking version, would there be apetitie for a PR with this upgrade?
